WHEN Amy Siu Yin received a fax from Hong Kong saying she had won the 1993 South China Morning Post Student of the Year Award, she could not believe her eyes. Amy, who was in New Zealand at that time, told Young Post : ''I was really shocked. It's incredible. I read the fax over and over again before I was finally convinced I had really won. It's too good to be true.'' ''The award is the highlight of my life. It's the highest honour for me. I'm really thrilled.'' The St Paul's Secondary School student, who scored eight As and a C in last year's Hong Kong Certificate of Education Examination (HKCEE), ranks number one in orienteering among her age group in the territory. Amy took up the sport about four years ago and is now the vice-chairman of the school's orienteering club, the event official of the School Orienteering Group and a member of the Orienteering Association of Hong Kong. She said orienteering was not only her favourite sport. It also helped nurture her personality and improve her inter-personal skills. ''I get to meet people of different ages from all walks of life. I used to be shy and quiet, but the sport has turned me into an active and outgoing person.'' According to her school principal, Mrs Diana Wong, Amy had made a lot of effort in improving her interpersonal skills and had changed from a rather conceited girl to a mature and considerate young lady. ''At the beginning, I was rather straightforward and I didn't know how to express myself. I took stock of my behaviour after my teachers and principal pointed out my weaknesses,'' she said. ''I started learning how to express myself by observing how important people like legislators and teachers talked. I followed them and it really worked.'' The motivated student is also an independent daughter. ''We never need to worry about Amy's studies. She is very self-reliant. I do hope we will be able to spend more time together,'' said Amy's businessman father, Siu Chong. Amy has a 15-year-old brother and her mother teaches German. The newly-crowned Student of the Year is planning to further her studies in Computer Science in the US. Computer is Amy's favourite subject. She hopes to become a successful programmer and produce computer games with her own graphics and music. Amy will receive a $20,000 Citibank scholarship and a Cathay Pacific round-trip ticket to any destination in Europe. The student said she would save the scholarship money for studying abroad and use the air ticket to attend an orienteering contest in Sweden in July.
